Italian replaces Garry Monk as manager
Swansea have confirmed the appointment of Francesco Guidolin as the club's head coach.
The former Udinese boss will work alongside interim manager Alan Curtis until the end of the season.
Swansea say Guidolin will have the final say on team selection.
"Although we recently appointed Alan Curtis as manager until the end of the campaign, he was aware and comfortable with the fact that we were still looking to bring someone in to assist if we found the right person," said Swansea chairman Huw Jenkins.
"We believe we have found that person in Francesco. He has an excellent record, especially with Udinese over the last few years. He created an Udinese side from a relatively small budget - compared to the rest of the league - that competed with the big teams in Serie A.
"He instilled a belief and motivation to compete and beat the best Italy had to offer. It is similar to what this football club is trying to do in the Premier League.
"He also has a wealth of knowledge of players throughout Europe which will be a big boost on our recruitment side; something we have been reviewing in a lot more depth over the last few months.
"When the need arose to look for a new manager or head coach, those characteristics stood out from a number of other potential candidates, together with the enthusiasm he has shown to come in and help us turn our season around and retain our Premier League status."
Curtis has taken charge of seven games since Garry Monk was fired, winning once.
They play at home to Watford in the Premier League later this evening.
